První záznam pestřenky Callicera aurata (Diptera: Syrphidae) v České republice

Abstract: Callicera aurata (Rossi, 1790) (Diptera: Syrphidae) was found on 31.vii.2023 in the Sovinecko Nature Park in the municipality of Dlouhá Loučka, in the locality Valšův Důl. This is the first reliable finding of this species in the territory of the Czech Republic. A female of the species Callicera aurata was found on flowering Dipsacus fullonum at the edge of an old, deciduous mostly oak (Quercus) forest. Since it was previously confused with the similar species Callicera aenea (Fabricius, 1777) a critical revision of previously published information on the occurrence of both species in the Czech Republic is provided. It was found that previously published information on the occurrence of C. aurata in the Czech Republic (Renema & Wakkie 2001, iNaturalist 2023) is incorrect. A review of published data and available material of the genus Callicera (43 males, 3 females) from the Czech Republic concluded that, of these two species, only Callicera aenea had been recorded in the Czech Republic up to now.
